Effect of total solids content in feed emulsion on the physical properties and oxidative stability of microencapsulated kenaf seed oil
Kenaf (Hibiscus cannabinus L.) seed oil has high potential to be used as edible oil. Despite the high content of polyunsaturated fatty acids, one of the major complications in commercialisation kenaf seed oil is its rapid oxidation, which leads to the production of undesirable toxic substances such...
